Studies have shown that low levels of serotonin are often linked to depression in individuals, and that these lowered levels can be caused by factors such as genetics, as well as a person’s environment, which may include physical and emotional trauma. Laser acupuncture can stimulate the release and synthesis of serotonin, using cold non-invasive lasers, as well as the release of endorphins, both of which can improve emotional wellbeing. Laser therapy can be used as part of a treatment program for depression that may also include physician-prescribed medication and/or psychotherapy, to offer a comprehensive process for recovery.
